Actually, they're not all exclusively pagan. Shaman is, and the high priest does carry pagan overtones, but the disciple, prophet and priest could easily be Christian. Frell, they could even double for Cult of the Damned from Warcraft 3. And once you get to elemental, it's fantasy territory.

I don't mind them. Could even add some more.

Not sure how the groups work, but could it be possible to use that to create separate rank paths?
